Shellexecute end?

I know someone out there knows this, because I've seen it myself somewhere...

How can I detect when a program I've shelled with ShellExecute has finished?

I need something that loops, if possible, so that I can keep it within a single form's sub to ease things along. Something along the lines of:

Code:

---

Do While (StillExecuting)
DoEvents
Loop

---

So that I can put in the code to execute after it's finished immediately after the loop.

Thanks in advance.

Try taking a look at this (I've never used it, but heard it works):

Here you go:

Code:

Public Type STARTUPINFO
    cb As Long
    lpReserved As String
    lpDesktop As String
    lpTitle As String
    dwX As Long
    dwY As Long
    dwXSize As Long
    dwYSize As Long
    dwXCountChars As Long
    dwYCountChars As Long
    dwFillAttribute As Long
    dwFlags As Long
    wShowWindow As Integer
    cbReserved2 As Integer
    lpReserved2 As Long
    hStdInput As Long
    hStdOutput As Long
    hStdError As Long
End Type

Public Type PROCESS_INFORMATION
    hProcess As Long
    hThread As Long
    dwProcessID As Long
    dwThreadID As Long
End Type

Public Declare Function WaitForSingleObject _
 Lib "kernel32" ( _
 ByVal hHandle As Long, _
 ByVal dwMilliseconds As Long) As Long

Public Declare Function CreateProcess _
 Lib "kernel32" Alias "CreateProcessA" ( _
 ByVal lpApplicationName As Long, _
 ByVal lpCommandLine As String, _
 ByVal lpProcessAttributes As Long, _
 ByVal lpThreadAttributes As Long, _
 ByVal bInheritHandles As Long, _
 ByVal dwCreationFlags As Long, _
 ByVal lpEnvironment As Long, _
 ByVal lpCurrentDirectory As Long, _
 lpStartupInfo As STARTUPINFO, _
 lpProcessInformation As PROCESS_INFORMATION) As Long

Public Declare Function CloseHandle _
 Lib "kernel32" ( _
 ByVal hObject As Long) As Long

Public Const NORMAL_PRIORITY_CLASS = &H20&
Public Const INFINITE = -1&
Public Const STARTF_USESHOWWINDOW = &H1

Public Sub ShellAndWait(sCmd As String, Optional WindowStyle As VbAppWinStyle = vbNormalFocus)
    Dim udtStart As STARTUPINFO
    Dim udtProc As PROCESS_INFORMATION
   
    udtStart.cb = Len(udtStart)
    udtStart.dwFlags = STARTF_USESHOWWINDOW
    udtStart.wShowWindow = WindowStyle
    CreateProcess 0&, sCmd, 0&, 0&, 1&, _
    NORMAL_PRIORITY_CLASS, 0&, 0&, udtStart, udtProc
    WaitForSingleObject udtProc.hProcess, INFINITE
    CloseHandle udtProc.hProcess
End Sub

---

Just call the ShellAndWait sub and pass the command line as the first argument and optionally the state for the window.

Code:

---

ShellAndWait "Notepad.exe", vbMaximizedFocus

---

If you want to call a DOS application please do so by calling the COMMAND.COM or CMD.EXE with the /C parameter for the application to "self close".

Code:

---

Dim sCmd As String

sCmd = Environ("COMSPEC") & " /C "
sCmd = sCmd & "c:\MyBatFile.Bat"
ShellAndWait sCmd, vbHide

---

Good luck!

Thanks, Joacim, your seemed real good but I got an error while running it.

I ended up using reeset's, which turned out to work just fine.

Thanks both :)
